Subject category Comment text
Deposit SOLITUDE TUNNEL EXPLORED THE DEEPER PORTIONS OF THE CITY ROCKS FISSURE. WINZES WERE SUNK DOWN TO 200 FT. BELOW THE TUNNEL LEVEL (9100 FT). MOST ORE CAME FROM BENEATH THE BUTTE MINE. ORE SAID TO FOLLOW SHOOTS WHICH MARK THE INTERSECTION BETWEEN THE FISSURE AND CERTAIN LIMESTONE BEDS. MOST PRODUCTION FROM FISSURE-REPLACEMENT DEPOSITS.
Deposit Discovery Year: EARLY 1900'S
